Investigation of Hydrogen Sulphide generation during maintenance dredging
Project description
The purpose of the project was to investigate the causes and sources of hazardous hydrogen sulphide concentrations arising during maintenance dredging of the approach channel to Jebel Ali Port in 1998 and to identify the distribution of the contaminant to enable the maintenance dredging to be completed. The first stage of the study involved reviewing the available information in order to define the problems encountered during dredging and to identify the scope of the field investigations required. The second stage involved field and laboratory investigations to qualitatively and quantitatively determine the potential for hydrogen sulphide generation during future dredging and recommend options for future channel dredging to mitigate the problems.
